Huawei Certified ICT Associate – Cloud Service v3 (HCIA-Cloud Service) — Question 1

Which feature can control the performance of specific applications or users in SAN storage?

Answer options

• A. Flow control management (QoS)
• B. Thin provisioning
• C. Level-2 cache (SSD cache)
• D. Storage tiering

Correct answer: A

Explanation

The correct answer is Flow control management (QoS) because it specifically manages and prioritizes performance for applications and users. Thin provisioning, Level-2 cache, and Storage tiering focus on resource allocation and optimization but do not directly control performance on a per-application or per-user basis.
